Why do websites ask for permission to use advertising cookies?

Show answer & explanation

Answer: Privacy rules can require consent before storing tracking cookies

The browser must charge a fee for storing each cookie — A cookie banner is not asking you to pay the browser to store a cookie. Cookies are small pieces of data used for things such as login sessions or tracking identifiers. Advertising-cookie consent concerns the use of that data, not a storage fee.

Privacy rules can require consent before storing tracking cookies ✓ — Privacy rules in places such as the UK require consent for advertising cookies because they can track browsing activity. A cookie can store an identifier that helps link visits together. Strictly necessary cookies can be exempt, and legal requirements differ by jurisdiction.

Cookies must be scanned for viruses before they can be saved — Consent is not a virus scan, and a cookie is data rather than executable software. A cookie can still carry a tracking identifier, so privacy choices matter even when no virus is involved. The banner addresses that data use.
